Application Summary AI generated
This standard specifies the stylus instrument procedure for calibrating ISO surface profile comparators and measuring surface roughness on blast-cleaned steel substrates. It is applied in industrial coating and painting operations, particularly in sectors like shipbuilding, heavy machinery, and structural steel fabrication, to ensure consistent surface preparation quality before applying protective coatings. The method provides a precise, quantitative alternative to visual or tactile comparison, enabling accurate verification of surface profile parameters critical for coating adhesion and performance.
